Autonomous heating systems

Autonomous heating systems are designed to supply residential premises with heat and hot water. Advantages of autonomous heating systems before central heating are obvious: you can turn the heating on and off, when you want, you also regulate the temperature in all the rooms yourself, and the availability of hot water in the house does not depend on utilities. But the installation of an autonomous heating system must be coordinated with the municipal services and get a special permit. Autonomous heating systems can not be installed above 10 floors.

Autonomous heating system consists of a boiler, batteries for heating, pipes (pipes), a variety of fittings (valves, valves, valves) and pumping equipment. The central part of the autonomous heating system is a boiler in which water is heated. Boilers are single-circuit and two-circuit. Single-circuit boiler serves only for heating the room, and double-circuit boiler It also heats the running water. Each type of boilers has its advantages and disadvantages. The two-circuit boiler is convenient because you have both independent heating and hot water with it, but if it fails - you will not have neither one nor the other. A single-circuit boiler can be combined with an expansion tank for heating water, but this combination will be more expensive than a dual-circuit boiler.

Double-circuit boilers are suitable for heatingpremises of a relatively small area - urban apartments and private houses of up to 200 square meters. m. For heating a larger room it is better to use a powerful single-circuit boiler, combining it with a boiler to heat water.

Boilers of autonomous heating systems are floor and wall. Wall mounted boiler suitable for a city apartment: it can be hung, say, in the kitchen, and a lot of space it does not take. But if you have a utility room in your house, you can put it there floor boiler.

By type of fuel Boilers are divided into gas, electric, solid- and liquid-fuel and combined. Choose the type of fuel is based on its price and availability. Gas fired boilers the most economical: the gas pipeline is practically in any apartment, and gas is a very cheap type of fuel. Heating with electricity - an environmentally friendly type of heating, with it there are no combustion products and exhaust fumes. AT solid and liquid fuel boilers use wood, coal, diesel fuel. Fuel for such boilers needs to be harvested in advance, but they are suitable for areas in which there are interruptions with gas and electricity. Combined boilers allow you to switch from one type of fuel to another, for example, from gas to coal. Such boilers will help you not to remain without heating and hot water in case of various accidents.

Autonomous heating systems are equipped with an automation system. This system helps to ensure safework of the boiler and helps to automatically maintain the optimal temperature in the house. Some automation systems require electricity for work, some do not. Many self-contained heating systems are equipped with room temperature sensors - such a sensor controls the operation of the boiler, based on the temperature of the air in the room. Many boilers for autonomous heating have function of reduced work: The boiler operates at full capacity in the morning and evening, when the owners are at home. In the afternoon, when the owners are at work, and at night when they are sleeping, the boiler goes into a mode of reduced fuel consumption.

Boiler output is calculated from the calculation of 1 kW per 10 square meters. m. area of ​​the room. Just in case, add 10-20% to the amount received. The power of the double-circuit boiler must be not less than 21 kW, because it also serves to heat water. Two-circuit boilers have two power modes: for heating the room and for heating the water. At full power, the dual-circuit boiler operates only when the water is heated.

When choosing a boiler, please note that it must be legal. The legality of the boiler for an autonomous heating system is confirmed by the availability of a number of documents:

• certificate of conformity;


• the conclusion of sanitary examination;


• permission to operate;


• guarantee book.

Lack of autonomous heating systems - theirlow self-sufficiency. An autonomous heating system with a gas boiler will pay for itself in the best case in five years. But still the advantages of autonomous heating systems outweigh the shortcomings, and more and more people are refusing central heating in favor of the autonomous.
